摘　　要：采用人工汗液浸泡法及火焰原子吸收光谱仪测试了316L不锈钢(/%:0.023C,17.57Cr,11.23Ni,2.03Mo)11种成型和表面处理工艺条件下的镍释放率。试验结果表明,50%压下率冷轧、1 050℃固溶,镜面抛光的316L不锈钢型材镍释放率只有0.02μg/cm^2/周,很好地满足了欧盟新标准EN1811:2011的要求。但是成型工艺(冷轧态,铸态)表面处理方式(粗糙度)、取样方式(纵、横向)都会直接影响材料的镍释放率,使其提高3~26倍。The release rate of nickel in stainless steel 316L （/% ： 0. 023C, 17. 57Cr, 11.23Ni, 2. 03Mo） processed with 11 kinds of shaping and surface treatment methods is measured by artificial sweat soaking method and flame atomic absorption spectroscopy. Test results show that the stainless steel 316L cold rolled with 50% reduction, solid solution treated at 1050 ℃ and mirror polished is only 0. 02 μg/cm2/week, finely to meet the European Union new standard EN1811 ： 2011. But the release rate of nickel is directly affected by shaping process （cold rolled state, cast state）, surface treatment method （roughness factor） and sampling method （longitudinal, cross section）, which may increase by 3 to 26 times.
